1 PT. Freeport Indonesia External Audit Responses to Recommendations Tailings TM1 PTFI should study the best locations for monitoring points in the downstream area of ModADA to replace Kelapa Lima and Pandan Lima. These new points will serve to monitor the retention performance in terrestrial part of Modified Ajkwa Deposition Area (ModADA) or if monitoring directly is not feasible, develop technically defensible method for estimating retention. TM2 Apply different methods to calculate the tailings retention in ModADA. Discussions with Ministry of Environment and Forestry (MoEF) are on-going to revise monitoring points and criteria considering regulatory requirements and topography. Appropriate methods to estimate retention are being discussed with the MoEF. Considering two methods-transect survey data, LIDAR in conjunction with density estimates.

TM4 Continue regular emergency response drills using and modifying (as necessary) the Tailing Incident Action Plan (TIAP) to develop the response routine necessary to quickly and effectively address potential levee breached in the future. Name of TIAP has been changed to TRMP Emergency Procedure Manual (TEPM). The TEPM covers emergency events such as floods or levee breaches. Geochemistry items are covered in the SOP TM Two table top drills and socialization with Emergency and other stakeholders have been completed in TRMP TM5 Modified upstream construction of the levee embankment in Zones 1/2 should continue to be employed to improve foundation conditions and reduce fill material.

Overburden OM1 Do a visual inspection of the Wanagon Drainage Drift (WDD) pipeline system and concomitant order of magnitude water balance for the Wanagon Overburden Stockpile (OBS) watershed. OM2 The Grasberg mine staff must confirm the recurrence interval and bedrock acceleration in relationship to the current and final slope angles for the East OBS. Pipeline is free from any obstruction. Changes in flow rates are closely correlated to rainfall, and not plugging of the system. Present water chemistry does not indicate plugging conditions. The bed rock acceleration evaluation was completed by Golder in January 2013, and was subsequently reviewed by LAPI ITB in January The exercise used a return period of 475 years (SB, 475 years RP, 10% PE in 50 years), with a 0.33g value determined for HighLand.

Additional facilities are planned and efforts to add additional contractors to carry out these programs are in progress. Programs currently in progress include plastic shredding for recycle in lowland and highland as well as additional biodiesel processing facility in the highlands. PTFI will continue to investigate additional recycling opportunities. These programs are limited by lack of local market for recycled materials.

Sediment control structures are being comissioned, and qualitative monitoring is being continued. Quarterly review meetings of fly ash utilization projects are planned to focus attention on improving this performance.
